Description

Technical Field

[0001] The utility model relates to the technical field of industrial construction industry, in particular to a maintenance hanger for an indirect air-cooling radiator. Background Art

[0002] Indirect air-cooled radiators are a key component of a thermal power plant's indirect air-cooling system. They serve as heat exchange equipment, cooling the circulating cooling water from equipment such as the turbine condenser. Common indirect air-cooled radiators are also known as cooling triangles. Each cooling triangle consists of two cooling columns (each containing multiple tube bundles), mounted vertically and at a specific angle.

[0003] The cooling column is composed of multiple tube bundles connected together. The tube bundle is the basic unit of an indirect air-cooled radiator and primarily consists of tube sheets, heat exchange tubes, and fins. The tube sheets are located at each end of the tube bundle, and are connected to the heat exchange tubes via expansion joints. The heat exchange tubes are circular tubes, and the fins are plate fins. To eliminate gaps between the tubes and fins and reduce thermal resistance, the tubes and fins are also connected via expansion joints. When the indirect air-cooled radiator is operating, circulating cooling water flows within the heat exchange tubes, while air flows outside. Convection heat transfer cools the circulating water.

[0004] The double-layer arrangement of six-row radiators offers the advantages of short flow paths, low water resistance, and high heat exchange performance. However, due to damage to the tube bundle during construction or frozen pipes due to various reasons during operation, they need to be hoisted out for repair during maintenance. Therefore, a dedicated hoisting device is urgently needed to facilitate this repair. Utility Model Content

One end of the first support beam 1 and one end of the second support beam 2 are detachably connected by a first bolt 6, which can be flexibly disassembled during the hoisting process, facilitating the hoisting operation. The first support beam 1 and the first triangular support frame 3 are connected by welding. The first triangular support frame 3 is welded to the lower side of the first support beam 1, which can improve the bearing capacity of the first support beam 1. The first triangular support frame 3 includes a first side support 31, a second side support 32 and a first bottom support 33, and the first side support 31, the second side support 32 and the first bottom support 33 are distributed in a triangular shape, wherein the first side support 31 and the second side support 32 are set as the two sides of the triangle, and the first bottom support 33 is set as the bottom side of the triangle. One end of the two side supports 32 is welded to the end of the first support beam 1 away from the second support beam 2, and the other ends of the first side support 31 and the second side support 32 extend obliquely from both sides of the first support beam 1 respectively. One end of the first bottom support 33 is welded to the extended end of the first side support 31, and the other end is welded to the extended end of the second side support 32 to achieve a triangular fit between the three. When the first side support 31 and the second side support 32 are connected, one end of the first bottom support 33 will cross and overlap with the first support beam 1, and the first bottom support 33 is welded to the first support beam 1 at the overlapping section.

[0028] Two sets of shackles 5 are installed on the first support beam 1. The upper part of the first support beam 1 is connected to the lifting equipment through the shackles 5, and the lower part is connected to the lifting counterweight through the shackles 5. Shackle supports 7 are also provided on the upper and lower parts of the first support beam 1.

[0029] The second support beam 2 and the second triangular support frame 4 are connected by welding. The second triangular support frame 4 can also ensure the bearing capacity of the second support beam 2. The second triangular support frame 4 includes a third side support 41, a fourth side support 42 and a second bottom support 43. The third side support 41, the fourth side support 42 and the second bottom support 43 are distributed in a triangular shape, wherein the third side support 41 and the fourth side support 42 are arranged as two sides of the triangle, the second bottom support 43 is arranged as the bottom side of the triangle, and the third side support 41 and the fourth side support 42 are arranged as the bottom side of the triangle. One end of each is welded to the end of the second support beam 2 away from the first support beam 1. The other ends of the third side support 41 and the fourth side support 42 extend obliquely from both sides of the second support beam 2 respectively. One end of the second bottom support 43 is welded to the extended end of the third side support 41, and the other end is welded to the extended end of the fourth side support 42, thereby achieving a triangular fit between the three.

The second bottom support 43 is welded to the second support beam 2, and the second bottom support 43 is arranged perpendicular to the second support beam 2. The first support beam 1 and the first triangular support frame 3, as well as the second support beam 2 and the second triangular support frame 4, are connected as a whole and work together to form a special double triangular support hoist for hoisting the lower cooling triangle 8 for radiator maintenance.

[0030] Better, see the attached Figures 1 to 3 As shown, in this example, a first support beam stiffening plate 9 is installed on the first support beam 1 to enhance the local stiffness of the first support beam 1 and reduce deformation, thereby improving the stability and load-bearing capacity of the first support beam 1. Similarly, a second support beam stiffening plate 10 is installed on the second support beam 2 to enhance the local stiffness of the second support beam 2 and reduce deformation, thereby improving the stability and load-bearing capacity of the second support beam 2.

The bolt cooperation between the second bottom support 43 and the bolt holes on the second support beam 2 and the second bolts 11 can ensure a reliable connection with the lower cooling triangle 8, and the lower cooling triangle 8 can be lifted out horizontally by balancing the lifting weight.

[0032] When the present application is in use, the first side support 31, the second side support 32 and the first bottom support 33 are welded at the lower side of the first support beam 1, thereby improving the bearing capacity of the first support beam 1. The second bottom support 43 is welded in the middle of the left side of the second support beam 2, and the bolt holes on the beam can ensure a reliable connection with the lower cooling triangle 8. The bearing capacity of the second support beam 2 is ensured by welding the third side support 41 and the fourth side support 42 at the lower side. The first support beam 1 and the second support beam 2 are connected by the first bolt 6 to form a detachable structure, which can be flexibly disassembled during the hoisting process, facilitating the hoisting operation. The upper part of the first support beam 1 is connected to the lifting equipment through the shackle 5, and the lower side is connected to the hoisting counterweight through the shackle 5.
